The BCA Green Mark Scheme was launched by the Building and Construction Authority (BCA) in January 2005 to promote environmental awareness in the construction and real estate sectors. It is a benchmarking scheme which aims to achieve a sustainable built environment by incorporating best practices in environmental design and construction, and the adoption of green building technologies.

This Green Mark Score Calculator will enable you to know the building performance of your project and its potential Green Mark scores to facilitate your planning process in support of the BCA Green Mark Scheme.

For submission in compliance with BC (Environmental Sustainability) Regulations 2008, please use the Green Mark (GM) e-Filing System. The Green Mark Calculator is not meant for regulatory submission on BP Apporval / TOP Approval.
